Naturopathy is a system of treatment that aims to cure diseases using natural elements freely available in nature. It is based on the belief that the human body has inherent self-healing powers and that diseases arise due to the accumulation of toxic waste matter in the body. The key principles of naturopathy include treating the whole patient based on their vitality and morbid matter levels, allowing acute diseases to help eliminate waste, and using natural foods and lifestyle practices as medicine and treatment over time to fully cure conditions.
